LOCKING DEVICE FOR GLASS-MOLDS.

SPECIFICATION forming part of Letters Patent N 0. 692,038, dated January 28, 1902. Application filed June 6, 1901. Serial No. 63,425. (No model.)

To aZZ whom it may concern:

Be it known that I, ALBERT STRUB, a citizen of the United States, residing at Beaverfalls, in the county of-Beaver and State of Pennsylvania, have invented certain new and usefulImprovements in Locking Devices for Glass-Molds, of which the following is a specification, reference being bad therein to the accompanying drawings.

In the operation of glass-molds, which are usually divided vertically into two parts hinged together, so as to permit them to be separated that the mold may be opened and the article removed, it is customary to employ a key or locking device for tightly closing the two parts of the mold together and holding them in this relation during the time the molten glass is being inserted into the mold-chamber and fashioned or shaped therein. It is a practical necessity that this key or locking device should be so constructed and arranged as to permit the rapid locking and unlocking of the mold; and my present invention has for its object toproduce a glassmold-locking device which is capable of very rapid manipulation and operates to securely hold the parts of the mold together.

It also has for its object to producea mold lock or key which may be used in connection with molds of different sizes, being adjustable, as will be hereinafter pointed out, to suit the requirements of use to which it maybe put in connection with different kinds and sizes of molds.

In the accompanying drawings, Figure 1 is a side View of a mold lock or clamp embodying my improvements and shown as applied to a glass-mold of ordinary construction. Fig.

2 is a top plan view. Fig. 3 is a vertical section taken on the line 3 3 of Fig. 1.

In the drawings, A A represent the two parts of a glass-mold, which are hinged together at A. The parts carry, respectively, the interfitting perforated lugs B B (J.

The mold represented is of the simplest construction; but it should be understood that my invention is adapted to be used in connection with glass-molds of a wide variety of kinds, shapes, and sizes.

a. 2 represents the key or eccentric pin forlocking the two parts of the mold together, it

being adapted to pass through the apertures in the lugs B and C of the mold. The keyis mounted in a centrally-disposed aperture in the carrier 4, whichin turn is seated in a socket or aperture in abracket or support 5. The portion of the bracket or support 5 which constitutes the wall of the socket in which is mounted the carrier 4 is provided with a slot 6, with which engages a pin or projection 7, carried by the key-carrier 4. This slot 6 is preferably formed with an inclined portion 8, a lower horizontal portion 9 of considerable length, and a short upper horizontal portion or seatlO. The carrier 4, in which is mounted the key, is free both to rotate and to slide longitudinally within the socket or. recess formed therefor in the bracket or holder 5, and it is provided with a handle 11, by which it is manipulated.

The bracket or support 5 is mounted upon a standard or arm 12, to which it is secured bymeans of a set-screw 13. The lower portion 14 of the standard orarm 12 is arranged at right angles to the main upright portion thereof, and the end of this portion is bent upward or disposed parallel to the main part 12, as indicated at 15.

The locking device is applied to the mold as follows: The short verticallydisposed portion 15 of the standard or stem is inserted into the aperture or perforation in the lower lug B of one of the sections of the mold. The bracket or holder 5 is then Vertically adjusted upon the rod or stem 12 until it rests upon the upper face of the upper lug B, with its aperture or recess, in which is inserted the key-carrier 4, directly in line with the apertures in the lugs B B. The parts of the mold-locking device being thus adjusted are secured together by the set-screw 13. In order to prevent any accidental or undesirable lateral movement of. the bracket or holder 5 relative to the lug B, upon which it rests, I employ dowel-pins 16, which fit into sockets in the parts 5 and B. After the adjustment just described has been effected the carrier 4 is turned so as to bring the stud or pin 7 into the lower horizontal portion 9 of the slot 6. The key 2 is then longitudinally adjusted within its carrier 4:, so that the cocentric portion thereof will be in position to properly engage with the lug C, and after .it is thus adjusted it is secured in position by means of a set-screw 17. The parts having been thus adjusted are in condition for use. When the mold is unlocked, the carrier is so moved as to cause the pin 7 to occupy the upper seat portion 10 of the slot, where it will be securely held. The parts of the mold may be then opened or closed by hand in the usual way. After the parts of the mold have been'closed by hand and it is desired to lock them the carrier 4ris turned by means of the handle 11 'so as to bring the pin 7 into the inclined portion 8 of the slot, and as the pin travels therein the carrier and the key are moved longitudinally downward, carrying the eccentric portion 3 of the key into the aperture of the lug O. The parts have been so adjusted that when the pin or projection 7 reaches the lower horizontal portion 9 of the slot the eccentric portion of the key has 'fully entered the recess in the lug O. A

further movementof the handle 11 results in a simple rotation of the carrier and the key, bringing the eccentric portion of the latter into operation to tightly force together and lock the two parts of the mold. A reverse movement of the handle causes an unlocking of the mold.

It will be seen that by means of the device which I have just described it is never necessary to withdraw the key from the parts in which it is supported, that the key is always in position for instant use, and that it is positively moved first in a longitudinal direction to cause the eccentric cam portion thereof to come into proper position for use and then rotated to cause the cam or eccentric to exert a wedging action to force the parts of the mold together and to lock them.

It will be seen that my lock or clamping device is adjustable and may be fitted to molds of many different sizes and shapes. If the lugs of the mold are thicker than the lugs represented in the drawings, it is only necessary to adjust the holder or bracket 5 to a higher position upon the stem or rod 12 and to adjust the key within its carrier so that when the projection or pin 7 is in the part 9 of the slot the cam or eccentric portion 3 of the key will be in position to operatively engage with the lug 0.

By means of this invention it is possible to largely reduce the number of locking or clamping means required in a large establishment, as a single'lock or clamp may be applied to many different molds.

It will be seen that after the key or eccentric pin 2 has been secured to its carrier by the set-screw 17 they become, in efiect and operation, an integral structure, and from this it is apparent that except for the adjustmentv der some circumstances might be found desirable. It is also evident that after thesupport or holder 5, in which the key in mounted, has been properly secured in place it becomes practically a part of one of the mold-sections, from which it is evident that certain features of my invention are applicable to a construction in which the holder or support for the key and its carrier might be integral with one section of the mold.
